I replaced the Deka brand AGMs in my GEM cart with these Duracells. So far/so good. Dekas are over $200 more(each)The weight of these seems to be comparable to the Dekas. Heavier means better when it comes to batteries .

First set lasted 5.5 years and were heavily used (300+ days per year) in an RV we use in business. Great batteries, well made, last long.

I installed three Duracell AMG 31 group batteries in my boat in May. One dedicated cranking & dash electronics, and two in series to power my 24V trolling motor. All hooked to a 3x10amp on-board charger/maintainer. Over 300 hours of use, including multiple days of hard use without charging and they have been flawless. Could not be more pleased.

I purchased two of these for my class A motor home. I hooked them in parallel which replaced the two wet cell batteries. Now I do not worry about checking water levels. The first day I installed them I ran the motor homes ventilation fan for about 6 hours and the battery charge panel showed that they were still close to fully charged.

I have several Duracell AGM group 31 , 27 and 24 . They work very well even 7 years later. Use a high amp Smart Charger and don't drain the battery dead . I have had some of these last me 10 years. All that being said converting to PO4 Lithium is much better in the long run.

We checked online ratings for rv batteries and decided on this for our travel trailer. It worked perfectly on our three week trip off the grid most days. Delivery to our local Sam’s club was fast and was ready for pickup as soon as we received the text message.

I bought this for a 2 week dry camping trip in the Smokies to replace a smaller size 27 Harris wet battery. Performance was generally disappointing in my 27’ RV under light loads of periodic use for 1-2 LED fixtures, water pump, and appliances that require a little DC to start the propane gas up (Fridge, Water heater). I would kill the generator at 8pm and fully charged, are above usage started until maybe 11pm. I turned off everything before bed. By morning my battery monitor was frequently reporting 40-50% remaining. This is not a true RV deep cycle battery. It’s a hybrid with both cranking and cycling design. I believe a pure deep cycle battery is a better way to go. This one will save you some money if you want an AGM to replace an older, smaller wet battery.

Just replaced 2 Duracell group 31 AGM Batteries on my boat the manufacturers date code was D3 on both batteries April 2013. 1 of the old batteries is still holding 12.28 volts and 480 MCA , the other sadly is only 10.56 volts and 0 MCA. These batteries were maintained with a MinnKota 3 bank on board charger designed for AGM Batteries. I wish they had lasted longer but they did outlast every other battery I have tried, 7 years is a long time with all the electronics I use on my boat.

I purchased 4 of these to use in my motorhome. $800 worth of batteries. The coach did not even get used. I installed the batteries 13 months ago in my motor home as starting batteries. The coach was never on the road and was only in storage with a trickle charge on the batteries the whole time. One month after the 1 year warranty expired they are shot. Sams will do nothing about it. I am going to do a youtube video and post it later.

Purchased 2 for my RV. Worked great the first few months then would not accept a full charge after 9 months. Returned for a full refund and then purchased 2 more. If these don't perform, I'll return and go with another brand. I've used other brands of AGM baterries in my RV and boat for almost 15 years and have had a couple of AGM batteries last over 10 years. Thank goodness for the 18 month warranty.
